Abstract

An arrangement for controlling exhaust pressure pulsation in a combustion engine including six cylinders. The engine also includes an inlet for supply of air to the cylinders, and an exhaust manifold for delivery of exhaust gases from the cylinders. The manifold is provided with a first outlet to an exhaust system and with a second outlet to a conduit for feeding exhaust gases back, via an EGR circuit, from at least one of the engine's cylinders to the inlet. At least one of the cylinders is adapted to enrich the exhaust gases with unburnt hydrocarbon with a view to regeneration of an exhaust gas post-treatment unit situated in the exhaust system. A special configuration of the exhaust manifold results in separation of regeneration gas from EGR gas in the exhaust manifold.
